These wannabe spiders use thorn-like weapons on their arms to attack small prey
|
view preview
Belonging to the class Arachnida, Amblypygids, also known as whip spiders or tailless whip scorpions, form a separate order of arachnids alongside the spiders, scorpions, and others. The name "amblypygid" means "blunt rump", a reference to a lack of the flagellum ("tail"). They are harmless to humans, and possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with pedipalps (thorn-like appendages), resulting in thorn-like puncture injury. ...

Ever seen a black flamingo?
|
view preview
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat. Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.

Memory-enhancing foods to help you study
|
view preview
There's more to studying than simply memorization and practice. It turns out that your diet also plays a pivotal role in recalling key bits of information, while keeping you energized and focused in the process. We're not talking about those scam-ridden supplements that promise a boost in brain power, but simple natural foods such as milk, nuts, seeds, rice, and oats. The nutrients found in these items help your study efforts by releasing natural memory enhancers called CCKs ( cholecystokinin). When CCK crosses the blood-brain barrier, it acts as a neurotransmitter associated with memory. Studies have shown that learning and memory processes are severely damaged (in rats) that genetically do not respond to the presence of CCK. And in people ...

Amazing blue mushroom
|
view preview
This is the sky blue mushroom ( Entoloma hochstetteri), a species of mushroom found in New Zealand and India. The small mushroom is a distinctive all-blue colour, while the gills have a slight reddish tint from the spores. The blue colouring of the fruit body is due to three azulene pigments. Entoloma hochstetteri is not edible, but whether or not it is poisonous is unknown. This species was one of six native fungi featured in a set of fungal stamps issued in New Zealand in 2002. It is also seen on the reverse side of the $50 bank note, issued by the Reserve Bank of New Zealand in 1990. Source: http://oddstuffmagazine.com/13-bizzare-mushrooms-from-around-the-world.html ...

The glue of the future, today
|
view preview
Before I begin telling you about this fascinating new glue (adhesive), there's a thing or two you need to know about the animal that inspired it all, the gecko. Geckos are small lizards that have the ability to run up walls and scurry across ceilings with the help of tiny rows of hairs on their feet known as setae. Setae generate a multitude of weak attractions (called Van der Waals forces) between molecules on the two surfaces that add up to a secure foothold. Unlike glue or tape, a gecko’s sticky feet attach and detach effortlessly, which made it a perfect case study for engineers to model. To create their artificial gecko adhesive, a Stanford team of scientists started by making silicone micro-wedges, which imitated gecko hair. They asse ...

Doctor of Osteopathy vs. Doctor of Medicine
|
view preview
The United States has two kinds of physicians, the Doctor of Medicine (MD) and the Doctor of Osteopathy (DO). Both use medicines, surgery, and other standard methods of treating disease. DOs, however, place special emphasis on problems involving the musculoskeletal system, which includes muscles, ligaments, bones, and joints. Nevertheless, both doctors receive virtually identical training, and are equally licensed in all 50 states. Osteopathic medicine holds that true health involves complete physical, mental, and social well-being, rather than merely the absence of disease. In this system, the body has a capacity for health that the physician helps the individual attain. The osteopathic physician, therefore, treats the whole patient, consid ...

Proboscis monkey nose
|
view preview
Meet the proboscis monkey ( Nasalis larvatus), a monkey only found in Borneo Island, Asia. The proboscis monkey is one of the largest monkeys native to Asia. It's very easily identified (for obvious reasons). The species has very pronounced sexual dimorphism, with the male being much larger than the female. Males also have much larger noses (the individual pictured is a male), but the noses of females are still very pronounced. The bigger the nose a male proboscis monkey has, the bulkier he will be — increasing his chances of attracting a large harem. Both sexes have bulging stomachs that give them the impression of having a pot belly. The proboscis monkey is assessed as Endangered in the IUCN Red List of Threatened Species and listed in Appen ...

Angiotensin-converting enzyme inhibitor
|
view preview
Angiotensin-converting enzyme (ACE) inhibitors are a remarkable class of drugs for treating hypertension – high blood pressure. These drugs work by interfering with the enzymes that convert an inactive chemical known as angiotensin I to an active form, angiotensin II. Angiotensin II increases the retention of salt and water in the body, raising blood pressure. ACE inhibitors interfere with, or inhibit, the formation of angiotensin II, resulting in relaxed arterial walls and lowered blood pressure. Since the release of the first ACE inhibitor in the 1980s, known generically as captopril, there are now several different ACE inhibitors available on the market. Many of them are also available in combination with other types of hypertension medic ...

Walking sushi

While this may look like sushi, it's actually Argentina's pink fairy armadillo. This rarely seen animal has silky white hair and a pinkish carapace; it ranges in size from 3.3 to 4.6 inches (84 to 117 millimeters) long, making it one of the smallest species of armadillos. The animal is also nocturnal and has the ability to bury itself in lightning speed given its long claws, which are an astonishing one-sixth the length of the body. ...

Would you ever disrupt this centipede family?

Take a good look at this if your stomach didn't already turn: this photo is a mother centipede protecting her young. The creatures appears to be an Amazonian giant centipede ( Scolopendra gigantean), which is the largest existing species of centipede in the world, reaching over 30 cm (12 in) in length. It is known to eat lizards, frogs, birds, mice, and even bats, catching them in midflight, as well as rodents and spiders. Sorry, in advance, if it gives you nightmares ...

Why do archaeologists and geneticists reach different conclusions?
|
view preview
An archaeologists is a scientist who studies human history by discovering and examining human remains and artifacts. The most common image of an archaeologists is someone on their hand and knees digging through dirt, carefully using a brush to dust off an artifact from the distant past. A geneticist, on the other hand, is someone who specializes in the science of genetics. This field of biology deals with the pattern of inheritance, molecular structure and function of genes, and gene behavior in context of a cell or organism. Both professionals are highly skilled, and use the same basic principles of science to test hypotheses, gather data, and make conclusions. However, why do archaeologists and geneticists sometimes reach different conclu ...

Can you spot the plants in this photo?

Lithops are succulents that have evolved to avoid being eaten by animals by blending in with pebbles and stones. In botany, succulent plants, are plants having some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. Succulent plants may store water in various structures, such as leaves and stems. ...
